2. Description of the Prior Art

There exists a need for a portable hygienic device for rectal or vaginal douching, or other cleaning by spray. Most known bidets are self-contained units, which are large and heavy, and are not of a portable nature. To meet this need, and to take advantage of preexisting toilets or water closets, bidet accessories have been developed for attachment to preexisting toilets or plumbing systems. Certain devices, both of the bidet type and for other purposes, are capable of holding liquid and dispensing the same under pressure.

U.S. Pat. No. 1,609,125, issued to M. Waldron Pitt on Nov. 30, 1926, discloses a fountain spray having a reservoir of liquid and a hand pump for building up the pressure within the reservoir. The pressurized liquid is dispensed from the reservoir to an applicator when a valve is opened. The reservoir includes indicia marking the level of the remaining liquid.

U.S. Pat. No. 3,602,921, issued to Harry M. Umann et al. on Sep. 7, 1971, discloses a portable bidet having a reservoir for holding a douching liquid and a hand pump for dispensing liquid. The pump expels that amount of liquid contained therein.

U.S. Pat. No. 3,808,608, issued to David Caplan on May 7, 1974, discloses a portable bidet which has a powered water pump, and which sits on an adjacent environmental surface. The liquid discharge nozzle is attach to the toilet.

U.S. Pat. No. 3,914,804, issued to Clarence O. Schrader et al. on Oct. 28, 1975, discloses a bidet accessory mountable on a toilet bowl, and features electrically powered water pressurization and heating. Different functions, such as for douching or for an enema, can be accommodated by changing water discharge tubes which support a nozzle.

U.S. Pat. No. 4,178,931, issued to Gene C. Lind on Dec. 18, 1979, discloses a portable bidet with an electrically driven pump. Lind has a thin walled housing assembly including two rectangular halves arranged in a telescoping fashion.

U.S. Pat. No. 4,259,754, issued to Jacob Bader et al. on Apr. 7, 1981, disclosing a bidet accessory having a liquid reservoir. A spring biased piston bears on the reservoir, thereby pressurizing the liquid. The reservoir is filled by attachment to a plumbing system with sufficient pressure to fill the reservoir while pushing the piston back against the force of the spring. A manually operated valve releases liquid for spraying.

U.S. Pat. No. 5,097,540, issued to Harold B. Lovitt on Mar. 24, 1992, describes a self-contained, hand-held bidet which may be pressurized by a hand pump.

Great Britain Patent Application No. 2,133,055 A for Albert McInally published Jul. 18, 1984; Great Britain Patent Application No. 2,233,553 A for Douglass G. McCandish published Jan. 16, 1991; and German Patent Application 3546,176 A1 for Josef Nemecek published on Jul. 2, 1987, all describe bidet devices of varying construction.

Several patents disclose electric heaters for heating the water before washing. U.S. Pat. No. 3,947,899, issued to Joseph D. Robinson et al. on Apr. 6, 1976, discloses a warm water supply kit with a pressure regulating valve. The device employs electric heating elements and a pneumatic control switch. U.S. Pat. No. 4,092,744, issued to Aristotel Butoi on Jun. 6, 1978, discloses an apparatus mountable on a toilet for washing a person's private parts. U.S. Pat. No. 4,622,704, issued to Jing-Yau Chung on Nov. 18, 1986, discloses a portable sanitary device with an electric heating element.

None of the above patent references, taken either singly or in combination, is seen to describe the instant invention as claimed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Turning first to FIG. 1, the hygienic spray apparatus of the present invention includes a spray bottle 10 which dispenses a stream of liquid on demand. A cap 12 houses a pump 14, a discharge port 18, and a pickup tube 20 which extends to the bottom of storage container 22. Cap 12 attaches to storage container 22 by friction, and preferably by mutual threading 24.

Storage container 22 is preferably made from a transparent or translucent material. Indicia 26 for measuring and for indicating a maximum preferred liquid filling level is included on storage container 22. A resilient member 28 is provided to cushion the bottom of storage container 22 and to improve frictional grip thereof on a supporting environmental surface.

Pump 14 may be any known suitable pump. One suitable pump is a forced air pump 14. Switch 36 activates motor 42 of pump 14. Motor 42 forces surrounding air into storage container 22 through air inlet 48 on the side of cap 12. Air enters storage container 22 through air inlet 48. Air inlet 48 is preferably a spring-biased, one-way check valve. The incoming air pressurizes the liquid in the storage container 22. The pressurized liquid is constrained to flow up through pickup tube 20, through a conduit 30 formed in cap 12, then exiting through port 18, which is open to the atmosphere. Depressing switch 36 again deactivates motor 42 of pump 14. Another suitable pump is a forced liquid pump in which the pump draws liquid from the storage container by suction force. The forced liquid pump will be discussed further in connection with FIG. 9. The suction force may be provided for forced liquid pump by any known method.

Pump 14 is preferably powered by rechargeable batteries 44. While any type of battery is suitable, rechargeable batteries, such as NiCad batteries, allow the user the opportunity to use a low voltage charger 49 to recharge from an electrical outlet. Female plug 46 on cap 12 can accept the male end 47 of low voltage charger 49. While male end 47 is mated with female plug 46, pump 14 is preferably disconnected from batteries 44. The pump is thereby precluded from operating while batteries 44 are being recharged. Pump 14 and batteries 44 are properly isolated to prevent contact with any liquid that may cause a short circuit.

Liquid flows out of cap 12 into a rigid discharge tube 54, seen in FIG. 2. Discharge tube 54 is insertable into port 18, and is retained therein by friction. Discharge tube 54 is preferably formed to include a horizontally arranged connecting section 61 to cooperate with port 18. Liquid in discharge tube 54 is ultimately discharged from nozzle 56 having a plurality of upwardly oriented discharge holes 58.

The present spray bottle 10 is preferably configured to cooperate with a toilet to serve as a portable bidet. With reference to FIGS. 6 and 7, spray bottle 10 is placed on a toilet bowl wall upper surface S or on a portion of a toilet seat S. Discharge tube 54 is formed to have a first section 60 arranged vertically downward, and a second section 62 projecting horizontally, radially away from storage container 22. Second section 62 is preferably substantially even with the bottom of storage container 22.

A third section 64 is disposed at a level lower than that of second section 62, preferably below the level of the top surface of toilet bowl wall S, and continues to project away from storage container 22. In this manner, discharge tube 54 clears toilet bowl wall or toilet seat S, while still reaching sufficiently far from spray bottle 10 such that spray from nozzle 56 will reach those body parts being treated.

In order to provide adjustment to reach of the spray, a sleeve 66 is slidably mounted on nozzle 56. By moving sleeve 66 appropriately, a user selects certain discharge holes 58 to be operative, others being prevented from discharging liquid.

Turning back to FIG. 4, an alternative embodiment discharge tube 54 is shown wherein nozzle 56 is not elongated as in the previous embodiment shown in FIGS. 2 and 3. In addition, no sleeve is required.

To accommodate those users who must insert a nozzle into the body, as for vaginal douching, another embodiment of a discharge tube is illustrated in FIG. 5. Discharge tube 68 includes a flexible section 70. Nozzle 56 is held selectively at variable orientations by a user even while spray bottle 10 is held at a constant orientation.

Spray bottle 10 and a selected discharge tube may be combined into a hygienic kit 72. As seen in FIG. 8, kit 72 preferably includes at least one refillable bottle 74 containing a therapeutic liquid. An absorbent material is provided for cushioning body parts and wiping spillage from spray bottle 10. A preferred absorbent material is cotton swabs 76, contained in an enclosure 78, such as a plastic bag.

Kit 72 provides many sanitary or therapeutic benefits which are frequently foregone when traveling. All necessary materials are included in a compact, light, portable package, and the apparatus is entirely independent of reliance upon plumbing systems.

FIG. 9 illustrates an alternate embodiment of the instant invention using a forced liquid pump 114. Switch 136 activates motor 142 of pump 114. Being located on the side of cap 112, one can easily activate switch 136 when spray bottle 10 is placed on toilet seat S as shown in FIGS. 6 and 7. Motor 142 creates a suction force for constraining the liquid to flow up through pickup tube 120, and then exit through conduit 130 and port 18, which is open to the atmosphere. Forced liquid pump 114 may create the suction force by any known method.

Pump 114 is preferably powered by rechargeable batteries 44. Female plug 146 can accept the male end 47 of low voltage charger 49. Pump 114 is preferably disconnected from batteries 44 while male end 47 is mated with female plug 46 to preclude operation of pump 114 while batteries 44 are being recharged.

It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
